Hi, I'm running the latest Burp Suite Pro (1.7.23) on Kali Linux rolling 2017.1. After installing "Header Analyzer" extension i'm unable to start it. I get an error: #### Traceback (most recent call last): File "<string>", line 1, in <module> ImportError: No module named os at org.python.core.Py.ImportError(Py.java:304) at org.python.core.imp.import_first(imp.java:755) at org.python.core.imp.import_module_level(imp.java:837) at org.python.core.imp.importName(imp.java:917) at org.python.core.ImportFunction.__call__(__builtin__.java:1220) at org.python.core.PyObject.__call__(PyObject.java:357) at org.python.core.__builtin__.__import__(__builtin__.java:1173) at org.python.core.imp.importOne(imp.java:936) at org.python.pycode._pyx1.f$0(<string>:1) at org.python.pycode._pyx1.call_function(<string>) at org.python.core.PyTableCode.call(PyTableCode.java:165) at org.python.core.PyCode.call(PyCode.java:18) at org.python.core.Py.runCode(Py.java:1275) at org.python.core.Py.exec(Py.java:1319) at org.python.util.PythonInterpreter.exec(PythonInterpreter.java:206) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at burp.id.<init>(Unknown Source) at burp.emc.a(Unknown Source) at burp.qg.run(Unknown Source) at java.lang.Thread.run(Thread.java:745) #### I have jython version 2.5.3-16 installed on my system. Jython jar (/usr/share/java/jython.jar) is also loaded in Burp. Any ideas how to enable this module? regards,

Hi Dmitri, This extension works well with Jython 2.7.0 (standalone) - available from http://search.maven.org/remotecontent?filepath=org/python/jython-standalone/2.7.0/jython-standalone-2.7.0.jar - could you upgrade to see whether this fixes your issue? Best regards, Adam
